Slab through conduit gate valves are designed and manufactured in accordance with API 6D and API 6A standards and specifically for on-off services. This valve is suited to withstand all type of process fluids, under high pressure and temperature conditions.
The valve design includes a rising stem which accommodates the upward and downward movements of the gate allowing it to open and close under the line pressure.
In normal operation, line fluid fills the cavity and the gate is lifted by the pressure generated from the flow path assisting the actuator spring to open the valve, resulting in a fail-open configuration.
Slab through conduit gate valves are piggable in the fully open position and generate pressure drop across the valve equal to the inside diameter of the connecting pipe.
